Description
MQ-5 Liquefied Gas, Methane, Coal Gas, LPG (liquefied petroleum gas) Sensor sensitive material is used to clean the air in the lower conductivity of tin dioxide (SnO2). When the sensor is in an environment in which the combustible gas , conductivity of the sensor increases when concentration of combustible gases in air increases.
Using a simple circuit can change the conductivity conversion of an output signal corresponding to the gas concentration.
MQ-5 gas sensor of high butane , propane, methane sensitivity, methane and propane can be better taken into account.
This sensor can detect a variety of combustible gases, especially natural gas. It’s a low-cost sensor for a variety of applications, suitable for home or industrial liquefied petroleum gas , natural gas, coal gas monitoring devices. Excellent resistance to alcohol or smoke interference.
- It adopts high quality double panel design with power indication and TTL signal output indication;
- It has DO switch signal (TTL) output and AO analog signal output;
- The TTL output valid signal is low. (When the output is low, the signal light is on, it can be directly connected to the MCU or relay module)
- The voltage of the analog output, the higher the concentration, the higher the voltage.
- It has good sensitivity to gas and natural gas detection.
- There are four screw holes for easy positioning;
- Product dimensions: 32 (L) * 20 (W) * 22 (H)
- It has a long service life and reliable stability
- Fast response recovery characteristics
Electrical Performance:
- Detection of gas: Liquefied gas/Methane/Coal gas/LPG
- Detection of Concentration: 300-10000ppm
- Input voltage: DC5V
- Power consumption (current): 150mA
- DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
- AO output: 0.1-0.3V (relatively non-polluting), the highest concentration voltage is about 4V
- Using the chip: AT89S52
- Crystal: 11.0592MHZ
- Baud rate: 9600
Dimensions
Special Reminder: After the sensor is energized, it needs to be preheated for about 20 seconds, and the measured data is stable. The heating of the sensor is a normal phenomenon, because there is a heating wire inside, if it is hot, it is not normal.
